There are a lot of specific openings in this other game that people have been playing for a while, many of which can require specific counters to beat against a skilled opponent or are high risk/reward, but nobody calls those cheese.

Calling a strategy cheese is an ad hominem argument.

Cheese builds in Starcraft are bizarre, unusual, or very meta builds that are designed for the sole purpose of being incredibly difficult to counter to a player that isn't aware they're being used, such as rushing the enemy base with SCVs as Terrans, which can be devastating against newer players who haven't posted scouts to let them know about incoming foes.

Chess allows you to see all of the opponent's pieces at all times and starts both players in an equal position. Players cannot hide their moves in order to prepare an unexpected attack that cannot be countered without advance knowledge.
